[0002] Nettle, a perennial herb, not only occupies a place in the ecological environment but also is widely used in the fields of food ingredients and traditional Chinese medicine. Its rich nutrients and various bioactive components, such as polysaccharides, flavonoids, polyphenolic compounds, etc., make nettle a popular research object in the fields of nutrition and medicine. Nettle has a wide range of applications in the medical field. Its effects of expelling wind and dredging collaterals, calming the liver and relieving convulsions, promoting digestion and relieving constipation, and detoxifying make it often used to treat symptoms such as rheumatic arthralgia, postpartum convulsions, infantile convulsions, hypertension, and indigestion. Regarding the extraction of the active ingredients of nettle, there are currently various methods that have been studied and applied, including but not limited to solvent extraction method, ultrasonic-assisted extraction method, enzymatic hydrolysis method, etc. Through these extraction methods, we can make more effective use of important components such as polysaccharides, flavonoids, and polyphenolic compounds in nettle, and further exert its application potential in the fields of nutrition and medicine.

[0003] In the prior art, a method for extracting and optimizing the extraction process of nettle polysaccharide from Urtica zayuensis with the publication number of CN119241736A belongs to the technical field of polysaccharide extraction. In the present invention, ethanol is added to the dried rhizome powder of Urtica zayuensis, and after heating and refluxing in a water bath, filtration is carried out. After collecting the filter residue, the ethanol is evaporated to obtain a defatted sample; after hot water extraction of the defatted sample, a filtrate is obtained; ethanol is added to the filtrate for alcohol precipitation, and after standing, the precipitate is separated. After the ethanol in the precipitate is evaporated, nettle polysaccharide is obtained. This method makes up for the blank in the research on the extraction process of nettle polysaccharide from Urtica zayuensis, and according to the extraction conditions explored in the present invention, the extraction rate of nettle polysaccharide can reach more than 10%, which can provide a basis for the research and application of new drugs of nettle polysaccharide.

[0004] However, when the existing nettle extraction device is in use, although it can perform better processing and extraction operations on nettle, when extracting and processing nettle, the feeding path of nettle is relatively fixed, and the effect of multi-path switching feeding for nettle is not high. Moreover, when switching the feeding of nettle, the pre-crushing and heating effect of the nettle to be fed is not high, reducing the heating efficiency of nettle in the extraction device, resulting in a longer heating time for nettle in the extraction device, and reducing the extraction and processing efficiency of the extraction device for nettle, which does not meet the usage requirements of people.
